本文着重论述了我国南方海相碳酸盐生油和可能生油岩的地质学和地球化学基本特征,即:碳酸盐生油岩的沉积学特征;碳酸盐生油岩的有机质数量特征;碳酸盐生油岩的演化特征;其他特征。本文通过对生油岩剩余有机碳、气态烃、族组分、干酪根形态、镜质体反射率等一系列数据的分析,进一步论述了我国南方碳酸盐生油岩的有机质丰度、有机质类型和有机质演化特点;指出了本区找天然气的潜力大于找油的潜力;同时对我国南方,其中特别是湘、鄂两省的油气普查工作提出了一些初步意见。
This paper focuses on the basic geology and geochemistry of marine carbonate carbonate oil source rocks and probable source rocks in southern China, ie, the sedimentary characteristics of carbonate source rocks, the quantitative characteristics of organic matter in carbonate source rocks Evolution characteristics of carbonate source rocks; Other characteristics. In this paper, a series of data such as residual organic carbon, gaseous hydrocarbon, ethnic composition, kerogen shape and vitrinite reflectance of source rock are analyzed. The abundance of organic matter, organic matter Type and characteristics of organic matter evolution. It is pointed out that the potential of finding natural gas in this area is greater than the potential of looking for oil. Some preliminary opinions on oil and gas census in southern China, especially in Hunan and Hubei Provinces are put forward.
